WR Sammy Watkins, Clemson (6-1, 211) Getting Watkins (below) and his playmaking ability aboard would go a long way toward explaining why the Raiders never got serious about adding DeSean Jackson in free agency. Could have the immediate impact A.J. Green had in Cincinnati.

OT Taylor Lewan, Michigan (6-7, 309) Generally regarded as the third best tackle behind Auburn's Greg Robinson and Texas A&M's Jake Matthews, the word is the Raiders think he might be the best of the three. Could also be an option if the Raiders trade back a few spots to land an additional pick.

DE Jadeveon Clowney, South Carolina (6-6, 266) Regarded by some as the most talented 4-3 end since Bruce Smith, Clowney has a reputation for occasionally going too fast in his car and not fast enough on the field. Still the favorite to go No. 1, he'd be hard to resist if he fell to No. 5.

QB Blake Bortles, Central Florida (6-5, 232) Conservative by nature, general manager Reggie McKenzie is more likely to go with the more prototypical passer than to gamble on someone like Johnny Manziel if he wants a quarterback-in-waiting behind Matt Schaub. Fresno State's Derek Carr is an option if the Raiders trade back.
